3. The location of each jacking point 3 is
indicated by a mark on the bottom edge
of the vehicle.
On Astra VXR and vehicles with
wheelarch trims 3 or after-market trims,
jacks may not be used 3. The vehicle
may be damaged.
4. Before positioning the jack 3, set it to the
necessary height by rotating the eye by
hand. Position the jack 3 at the front or
rear so that the jack claw spans the
vertical base and grips in the recess in
the vertical base. Make sure it is properly
positioned.
The jack base must be on the ground
directly below the jacking point in a
manner that prevents it from slipping.
Attach crank to eye of threaded rod and
turn crank to raise vehicle.
If this is not the case, carefully lower the
vehicle immediately and reposition the
jack.
5. Unscrew wheel bolts and wipe clean with
a cloth. Then apply a light coating of
grease to the wheel bolts. Do not grease
the thread of the bolts. Do not put the
wheel bolts down in a location where
they may become soiled.
If the wheel bolts have retaining
washers 3, they must not be removed.
